Question

usha swims in 50m long pool she covers 100m in a 1min by swimming one end to other and back along the same straight path .find the average speed and velocity​

Answer 1

Answer :

3ms−1 ; zero

Solution :

Here , total distance travelled , s=180m , time taken , t=1min.=60s

Average speed =st=18060=3m/s

In swimming from one end to the other and back along the same straight path , displacement =0.

Average velocity =displacementtime=zero
